All,
Thanks for feedback regarding "QRG on 160 in North and South America"
It seems that i.e. 1821.5 an up to 28.5 on odd QRG is ok for USA and EU
For i.e March 10th the 45 to 60 min greyline window in JA, TX could be as
low as 1813.5 and lsn up.
For the ZL guys it is just after our SS and Static could be dominant
however, 7P8 is very far south so maybe it is not that bad in the end.
